[0016] like Figure 1-5As shown, this utility model provides a technical solution: a filter material testing device based on the oil mist method, including a test chamber 1, a sealing door 2 located at the front of the test chamber 1, a feed pipe 4 connected to the left side of the test chamber 1, a first photometer 5 installed through the feed pipe 4, a discharge pipe 6 connected to the right side of the test chamber 1, a second photometer 7 installed through the discharge pipe 6, and a connecting assembly 3 located on the side of the test chamber 1. The connecting assembly 3 includes an installation mechanism 31 located inside the test chamber 1, a filter mechanism 32 located at the end of the discharge pipe 6, and valves located at the ends of both the feed pipe 4 and the discharge pipe 6 near the test chamber 1. The installation mechanism 31 includes the test chamber 1 fixedly installed inside the test chamber 1. The internal mounting base 311 has a mounting groove 312 inside, and a mounting frame 313 is inserted into the mounting groove 312. Filter material 314 is fixedly installed inside the mounting frame 313. A slot 315 is provided on the upper part of the mounting frame 313. A first sealing ring 316 is fixedly connected to the inner wall of the mounting base 311. A movable groove 317 is provided inside the mounting base 311. A movable block 318 is slidably connected to the inner wall of the movable groove 317. An inclined locking block 319 is fixedly connected to the bottom of the movable block 318. A connecting rod 3110 is fixedly connected to the upper part of the movable block 318. A first spring 3111 is fixedly connected to the inner wall of the movable groove 317. A pull rod 3112 is fixedly connected to the top of the connecting rod 3110 through a connecting block.

[0017] In this embodiment, the inclined plate block 319 is movably connected to the movable groove 317 and the slot 315. One end of the first spring 3111 is fixedly connected to the movable block 318. Through the cooperation of the mounting base 311, mounting groove 312, mounting frame 313, filter material 314, slot 315, first sealing ring 316, movable groove 317, movable block 318, inclined plate block 319, connecting rod 3110, first spring 3111, and pull rod 3112, it is convenient to manually replace the filter material 314, thereby speeding up the testing efficiency of the filter material 314. Moreover, the replacement operation is simple and convenient, increasing the applicability of the device.

[0018] Furthermore, the top end of the connecting rod 3110 extends through the movable groove 317, and the first sealing ring 316 is disposed in the gap between the mounting groove 312 and the mounting frame 313.

[0019] When using the device, the mounting frame 313 is first manually inserted into the mounting groove 312. When the mounting frame 313 enters the mounting groove 312 and presses against the inclined plate block 319, the inclined plate block 319 can be pressed into the movable groove 317. After the mounting frame 313 and the mounting groove 312 are fully engaged, the movable block 318 can move the inclined plate block 319 outward under the action of the first spring 3111, so that the inclined plate block 319 can engage with the slot 315, thereby fixing the mounting frame 313 in the mounting groove 312. This completes the installation of the filter material 314. Then, the oil mist is introduced into the feed pipe 4, which can then be introduced into the test chamber 1. The oil mist that has passed through the filter material 314 can be discharged from the discharge pipe 6. With the cooperation of the first photometer 5 and the second photometer 7, the concentration of the oil mist before and after filtration can be detected, and the filter material 314 can be tested. Example

[0020] Based on Example 1, a preferred embodiment of the filter material testing device based on the oil mist method provided by this utility model is as follows: Figures 1 to 5 As shown: The filtration mechanism 32 includes a filter box 321 connected to the end of the discharge pipe 6. The filter box 321 has a connecting groove inside, and a connecting frame 322 is inserted into the connecting groove. A filter plate 323 is fixedly installed inside the connecting frame 322. A pressure groove 324 is opened on the upper part of the connecting frame 322. A second sealing ring 325 is fixedly connected to the inner wall of the filter box 321. An inner groove 326 is opened inside the filter box 321. A pressure column 327 is movably connected inside the inner groove 326.

Through the cooperation of the filter box 321, the connecting frame 322, the filter plate 323, the pressing groove 324, the second sealing ring 325, the inner groove 326, the pressing column 327, and the second spring 328, the exhaust gas can be filtered, preventing the exhaust gas from being directly emitted to the outside world and causing pollution to the external environment, thus further increasing the applicability of the device.

[0022] Furthermore, the second sealing ring 325 is disposed in the gap between the connecting groove and the connecting frame 322.

[0023] When the exhaust gas enters the filter box 321 from the discharge pipe 6, it can be filtered by the filter plate 323 to prevent the exhaust gas from being directly emitted to the outside and polluting the external environment. Furthermore, when it is necessary to disassemble the connecting frame 322, it can be manually pulled out, which facilitates manual cleaning of the filter plate 323. When installing the connecting frame 322, it can be manually inserted into the connecting groove. Then, under the action of the second spring 328, the pressing column 327 can be pressed against the pressing groove 324, thereby pressing and fixing the connecting frame 322 in the filter box 321, thus completing the installation of the connecting frame 322.
